Abstract:
For a new road set in a region where an existing road is not present in map data, a road associated information setting unit 13 determines and sets road associated information to be applied to a road link of a new road on the basis of movement history data relating to a plurality of moving bodies stored in a movement history storage unit 14. Accordingly, the road associated information on the new road is automatically set on the basis of the movement history data relating to the plurality of moving bodies, and hence a worker is no longer required to execute on-site investigation or manually generate road associated information.

Abstract:
A smartphone into which an application is installed includes a first and second authentication processing unit. The first authentication processing unit is configured to determine whether or not a current activation time of the application is past expiration time; permits authentication if the current activation time is not past the expiration time; and denies authentication if the current activation time is past the expiration time. The second authentication processing unit is configured to determine whether or not the current activation time is after previous activation time; permit authentication if the current activation time is after the previous activation time; and deny authentication if the current activation time is not after the previous activation time, wherein second authentication processing allows authentication to be denied if the current activation time (tampered and unauthorized activation time) is time before the previous activation time, as a result of turning back an internal clock of the smartphone.
